Madonna did her usual post-workout walk all the way home (more like down the street) to her home in London. The singer is starting her Hard Candy promo tour and it included a radio interview the other day where she dishes on the title of her album, the infamous B12 shot with JT, and what kind of music her kids listen to. Madonna said Lourdes loves Britney and then they spoke about how the paparazzi is making life difficult for Brit. Madonna even declared to the host, "Let's go save her." You got to love that she clearly still cares about the younger pop star. You can listen to the whole interview here and expect a lot more from Madonna this month and this summer when she said she'd be living in NYC.
